Cheap Disposable Meat Toilet
There wasn't much to watch. The videos of sis getting fucked by OP clients... they were like real-life hardcore porn. So stimulating that I came right away.
Checking the length, there were nearly two hours of footage total. Skipping the greetings and the part where sis asks them to film her getting fucked like in porn, the videos jumped straight into the action: sis naked, surrounded by the men.

One guy bends her over and pounds her from behind in doggy style while another shoves his dick in her mouth, silencing even her protests...
"Mmph... mmph!"
"Hah... hah... ah! Fuck, this is amazing...!"
The remaining guy gropes her tits and ass—parts not yet claimed—while filming the whole violent setup. It felt just like those amateur Japanese first-person porns from sites like MyX. Compared to polished AV from big studios, the amateur directing was crude and the quality low, but the raw realism and on-site intensity made it hugely popular.
Exactly like that. Except the star was standing at attention right in front of me.
The guys in the video chattered away, thrilled at filming their own AV-like scene.
"Whoa, fuck... first time a whore in an OP asks us to film her herself? And she wants graffiti too, lol."
"Yeah. She's a real slut, huh? Heh... hey, squeeze that pussy tighter... yeah... hah..."
"Hnng... hah... ah, ah, ah...!"
"Fuck, she's loving it even as we go rough, lmao."
They kept talking shit right in front of her, rotating positions: the guy fucking her from behind moves to her mouth, the cameraman takes over pounding her pussy, the one in her mouth grabs the phone to film. A full-on gangbang rotation.
Sis in the video, getting passed around by faceless men.
And then...
"Hey, check her stomach. She said graffiti's okay too?"
"Fucking insane... so hot. First slut ever to ask for that."
The whore begs to be filmed getting fucked, already has some weird graffiti on her belly... and after sex, she asks for star ratings? How would the guys react?
"Some kinky play?"
"Fuck, maybe her boyfriend knows she's a whore and made her do it? Lol."
"Probably. Bet he told her to get filmed too."
Spot on, surprisingly. Not her boyfriend, but I was the 'master' owning sex slave Yeon-woo Lee.
And sis Yeon-woo... followed my orders, requesting humiliating plays from the men.
Fuck, those bastards had a blast.
The 'missions' I'd excitedly invented—these random guys playing with my cousin sis, my sex slave so deliciously—stirred a twinge of jealousy...
"Ah, fuck, so hot... sis, how'd it feel getting gangbanged and graffitied by those pricks? Huh?"
"...D-don't know..."
"Bullshit. You got turned on watching the video too, right? Real deal, getting off like a slut during a gangbang?"
"..."
But bigger than the jealousy was the thrill—a murky pleasure overwhelming it. Excited by jealousy and that darker ecstasy, I groped sis's body like a toy, immersed in the video.
How would these beasts handle her? Obvious. Rougher and rougher. Like me.
Resuming the video with that thought, sure enough, the guys grew feral, pushing beyond permitted plays on their own.
Spanking her ass nonstop while pounding from behind, yanking her hair for brutal thrusts, shaking her head while face-fucking her till she gagged dangerously hard—but ignoring it. Shoving the camera lens right into her wrecked, creampie-flooded pussy for close-ups...
"Can I take pics too? What? No? Fuck that—you asked for filming first, lol."
"Just no face."
"Whoa, fuck, I creampied her pussy so much."
"Mine's mixed in there too, bitch."
"Fuck, feels nasty. Wonhyo-level skull cum."
"Haven't heard that in ages?"
Usually, even pros draw lines—cross them, get blacklisted. My OP-experienced friend(?) Yong-ho Jo said so, and he's the expert. Probably.
But with the perfect excuse, these guys unleashed their cruel, violent sides. They saw sis not as a regular whore, but a filthy slut okay to abuse.
Even veteran OP girls avoid gangbangs—they're exhausting. Sluts who love sex still do one client per hour max; back-to-back wrecks you.
What if a whore offers gangbang service? 'Hardworking pro'? (X) 'Filthy slut ripe for abuse'? (O)
Yeah. So they treated sis like a cheap disposable meat toilet... defiling her every way, like a toy. Like me.
"Sis. Getting fucked by multiple guys at once—honestly fun, right?"
"...N-no... didn't enjoy it..."
"Really? So you hate it but do it for cash? No lies?"
"...Th-that's..."
"Hard to buy—you looked like you loved it."
"..."
Shoving the video in her face, sis went silent. Because—
"Haaah! Haaang...! Ah! Aaaahh!!"
—getting passed around by the three 'group clients,' she screamed like a bitch in heat. Nonstop.
"Screaming like that, the whole hallway hears, right?"
I'd been to her 'workplace' (OP)—soundproofing's iffy. This volume? Echoes everywhere.
Thinking that, I sat the tense, rigid sis on the bed, hugged her from behind, and whispered sweetly. Curious about her thoughts.
"Be honest. Why'd you cum so hard?"
"..."
"Why's getting gangbanged by multiples feel good? Spill."
Voice sweet, but my two fingers slithered snake-like into her seated cave. Primed to wreck her fragile depths anytime. Gently stroking inside till it squelched, teasing her slutty pussy—fucked 16 times in three hours—demanding answers...
She hesitated, then confessed honestly.
"...Got heated and sensitive mid-sex... then no break, just pounded... c-couldn't help it."
"Couldn't help it? So not 'cause you're a slut—just body reaction? That's your excuse?"
"..."
"Pfft. Still got pride, huh. Think you're still the rich princess? But really, you love gangbangs from three guys—hate admitting you're a filthy pussy slut. 'Not me, too classy'? Right?"
"..."
Sis clamped her lips shut. Hit the nail on the head—frustrated, humiliated expression. And humiliated by my tongue's assault, feeling deep contempt... yet aroused by it. A delicious mix.
Wanting more shame from her—like in the academy storeroom—I deliberately licked her face, dirtying it.
"Hah... hah... watching sis get fucked by others... pisses me off..."
"..."
"Pisses me off but so fucking hot. Driving me crazy."
"..."
"Why's that? Huh?"
My words were sincere. I'd ordered her to get fucked by others and film it... but a three-man gangbang? Her going wild in ecstasy? Jealousy hit, but a murkier pleasure dominated my mind.
Forced submission via blackmail, but as a guy, possessiveness was natural.
Yet... this twisted thrill watching my woman get railed. Why bigger than jealousy? Jealousy spiced it, making the primal pleasure sharper.
What is this? Why? Even I was confused.
Whatever...
"From now on... always film when other guys fuck you. Got it?"
"..."
"Answer."
"...Y-yes... understood..."
Her face licked humiliatingly, eyes vacant, mechanical reply soulless.
...Not satisfying.
"Hey. Feels shitty?"
"...Huh? N-no... Master..."
"Feels shitty, though? Tell Jin-woo? Send this video... hide it's you, as fap bait?"
"...Gasp, th-that..."
Ah. Side effect of long virgin shut-in life. Solo jerking escalated to extreme bait. Brain rotted into pervert trash despite the body.
Cousin sis, former social queen oblivious to hardcore hentai ruin porn, took my words dead serious—instantly swapped robotic fear.
That face? Perfect. Scared? Good. No attitude—be my faithful fucktoy.
"Jin-woo sees his sis gangbanged by three studs... imagine. How hot? Your brother secretly fapping to his blood sis selling her body... thoughts?"
"N-no! Please don't... I'll obey... p-please...!"
Ah... fucking delicious...! This reaction's to die for...!
This bitch. Treasures her lil bro? Just imagining him fapping to her twists her in ecstasy...
...Wait, ecstasy?
"Ah, you fucking slut."
"...Huh?"
"Why's your pussy wet imagining your brother using you as fap fodder?"
"...Wh-what..."
"Don't deny. Talking Jin-woo makes your slut hole clench all gummy?"
"N-no...!"
"Shh. Quiet. Dad hears, you own getting caught bare-assed rolling with cousin bro?"
"...Hic."
Overexcited, I grabbed Yeon-woo this bitch's hair, slammed her roughly on the bed... and worked the fingers still buried in her pussy.
"Hnng...!"
"Say it."
"...Wh-what...?"
"Imagined Jin-woo fapping to your video, right?"
"..."
"Admit. Bro jerking to sis vid... turns you on? Huh?"
"...N-no... hnnng...!"
"Bullshit? Pussy juice flooding now... fucking deluge?"
Partly from my wriggling fingers, sure—but mentioning 'Jin-woo,' her pussy spasmed octopus-like, squirting floods of nectar.
Really creaming at the thought of her real bro fantasizing... using blood sis as jerkbait? Insane...!
Ultra-aroused, I whipped the special correspondent fingers front-back fast in her depths... then shlorp!
Pulled them out.
"Hah. Slut. Fucked soaked it."
"...Hic...!"
Literally wrecked fingers. Slick with her juices... mixed with the guys' suspected cum, stringy nasty mucus dangling threads.
"Fuck... hey, suck it clean, slut."
"...!"
"Fuck... 16 creampies, endless supply, huh? Still sloshing in your gut. Filthy as hell."
I shoved the filthy fingers in her mouth, made her suck clean. Slut hesitated—still thinking she's prim miss—but forced in, she gave up, slurping her nectar-cum slime mix.
Fucking bitch. Cumming to bro thoughts. Watching that nasty, yeah? Bro's precious, huh? You're made for this treatment. Hah... hah...
Eyes bloodshot hyperventilating, vision tinting red... I gripped her throat as she sucked my hand, whispering.
"Hey. Mount me. Shake yourself."
"...Guhk... c-can't... breathe..."
"Can't make me cum in 5? Video to your bro. Got it?"
"...!"
